It doesn't matter that we outpace them, there isn't a huge gap between Ireland, Canada and the U.K. and the United States. A 3%-5% change for a 50%-100% increase in minimum wage and introduction of more social safety nets isn't really helping your case. I will ask again:
Why does the United Kingdom, Ireland, Canada, etc. have such high numbers of single-parent households, guy? They have substantial safety nets and relatively high minimum wages.
They have the high standard of living you proclaim would create stable families, yet are close to the United States in terms of single-parent households. You cannot just ignore them as if they don't matter - that's cherry picking.
